Key facts at a glance

what is a power supply and why it matters

A power supply, or PSU (power supply unit), gives power to every PC part. Wattage is the total power the PSU can deliver, measured in watts. If your parts draw more wattage than the PSU provides, the PC will shut down or fail to boot.

Efficiency tells you how much mains power is converted to PC power and how much is wasted as heat. Efficiency grades include 80 Plus Bronze and 80 Plus Silver. A Bronze unit wastes more power as heat than a Silver unit at the same load. Modularity means whether cables are fixed to the PSU or detachable. Non-modular PSUs have fixed cables, so excess cables may stay inside the case. Modular PSUs let you attach only the cables you need. Active PFC (power factor correction) improves electrical stability by making the PSU draw power more cleanly from the mains. Active PFC values above 0.9 are common in the listed models, which helps during unstable grid voltage and long cable runs.

• Wattage examples from TechCure stock: 550 W, 650 W, 750 W.
• Efficiency examples from TechCure stock: 80 Plus Bronze, 80 Plus Silver.
• Modularity note: listed models are non-modular.
• Active PFC example: listed Gigabyte and Cooler Master units report active PFC (>0.9 typical).

what is new or relevant in 2026 for buyers

ATX 3.1 and ATX12V v2.31 are versions of the power supply standard that define connectors and how the PSU delivers power to modern components. ATX 3.1 adds a new 12V rail behavior and better handling of sudden current spikes from high-end graphics cards.

Which listed PSUs match these standards matters when you plan a modern GPU or a multi-GPU display setup for trading. From the given models, Cooler Master MWE 550 V3 is explicitly ATX 12V Ver. 3.1, so it supports the newer connector and transient response improvements. Gigabyte P550SS is listed as Intel Form Factor ATX 12V v3.0 and noted compatible with ATX 3.1, so it also meets the newer requirements. The Gigabyte P650B models are listed as ATX 12V v2.31, so they follow the earlier Intel spec and will work for many builds but may not include the ATX 3.1 transient features. The Ant Esports models in the facts do not declare ATX 3.x or v2.31, so their exact ATX version is not announced in the provided data.

• Use ATX 3.1 or ATX v3.0 PSUs if you plan a recent high-power GPU or many-display trading rigs; Cooler Master MWE 550 V3 and Gigabyte P550SS meet those newer specs according to the listed data.

how to choose a PSU step by step

Step 1: estimate wattage. For a heavier build or many drives, a 650W PSU such as the Gigabyte P650B (650 W, ₹4,944 or ₹4,700 listing) gives more headroom. The Ant Esports RX750 (750 W, ₹4,190) is an option when you plan larger upgrades but still want to stay under ₹5,000.

Step 2: pick efficiency and check ATX version and connectors. Prefer 80 Plus Silver over Bronze when price allows because Silver wastes less power; the GIGABYTE P550SS is 80 Plus Silver and ATX 3.x compatible, so it handles modern GPU current spikes. Bronze units listed include the Gigabyte P650B models, Cooler Master MWE 550 V3, Ant Esports RX750 and RX550. Check ATX version on the label: Cooler Master MWE 550 V3 is ATX 12V Ver. 3.1 and Gigabyte P650B is ATX 12V v2.31; choose 3.1 if you plan a modern GPU.

Step 3: prefer active PFC and weigh modularity trade-offs. All listed models note Active PFC (>0.9 typical) or Active PFC, which helps with unstable grid voltage. Non-modular PSUs are cheaper and all listed options are non-modular, so expect fixed cables inside the case. If you need cleaner cable routing, budget for a modular model outside this list or accept the simpler fixed-cable layout.

• Before buying, match the PSU wattage and ATX version to your planned parts, check efficiency grade for running costs, and accept non-modular savings if cable management is not critical.

what matters most for gaming, editing and trading PCs

Wattage is the first priority for gaming, editing and trading rigs. The Gigabyte P550SS is 550 W and fits many mid-range gaming or light video-editing builds. For heavier editing with many cores or for upgrades, choose 650 W like the Gigabyte P650B (650 W, ₹4,944 or ₹4,700). For trading rigs with many screens and extra drives, pick even more headroom; the Ant Esports RX750 gives 750 W at ₹4,190 and works where many monitors and PCIe devices draw extra current.

Efficiency matters for long daily use. 80 Plus Silver wastes less power than Bronze, so the GIGABYTE P550SS (80 Plus Silver) will run cooler and use less mains electricity than Bronze units during long sessions. Bronze models here include the Gigabyte P650B, Cooler Master MWE 550 V3, ANT ESPORTS RX750 and RX550. ATX version affects compatibility with modern GPUs and sudden power spikes. ATX 3.1 or ATX 3.x support improved transient response for newer graphics cards. The Cooler Master MWE 550 V3 is ATX 12V Ver. 3.1 and the GIGABYTE P550SS lists ATX 3.x/12V-2x6 compatibility, so they suit modern GPUs. The Gigabyte P650B is ATX 12V v2.31 and works for many builds but lacks ATX 3.1 transient behavior.

• Active PFC (>0.9 typical) is present in the listed Gigabyte and Cooler Master models and helps with unstable grid voltage and long runs.

budget options and price-based picks under ₹5,000

Here are budget picks under ₹5,000 with a short recommendation for each. Gigabyte P550SS ₹3,746 (Silver, 550W) is 80 Plus Silver and lists ATX 3.x compatibility, so it wastes less power during long use and handles modern GPU current spikes. Ant Esports RX550 ₹3,200 (Bronze, 550W white) is a white, non-modular 550W Bronze unit that fits mid-range builds on a tight budget. Ant RX750 ₹4,190 (750W Bronze) gives more headroom for multiple drives or future upgrades while staying under ₹5,000. Cooler Master MWE 550 V3 ₹4,389 (ATX 3.1 550W) is ATX 12V Ver. 3.1 and suits modern GPUs that need better transient response. Gigabyte P650B ₹4,700, ₹4,944 (650W Bronze) offers higher continuous wattage if you want extra margin for a heavier build.

All listed units are non-modular and list Active PFC, so expect fixed cables and better behaviour on unstable grids. Choose the P550SS if you value efficiency and lower waste during long gaming or editing sessions. Choose RX750 or P650B if you need raw wattage for many drives, monitors or future CPU/GPU upgrades. Choose the Cooler Master MWE 550 V3 when ATX 3.1 compatibility is the deciding factor and you still want a 550W unit under ₹5,000.

• Gigabyte P650B ₹4,700, ₹4,944-650W, 80 Plus Bronze, non-modular

common mistakes to avoid when buying

Buying too little wattage is common. Do not pick a 550 W PSU if you plan many drives, multiple monitors, or a future CPU/GPU upgrade. The Ant Esports RX750 (750 W) and Gigabyte P650B (650 W) offer clear extra headroom for trading rigs with many screens or heavier editing. Wattage headroom keeps the PSU from running at high load, which matters during long sessions and when many components draw power at once.

Check the ATX version. ATX 3.1 or ATX 3.x helps with sudden GPU current spikes, which some modern graphics cards cause. The Cooler Master MWE 550 V3 lists ATX 12V Ver. 3.1, and the GIGABYTE P550SS lists ATX 3.x/12V-2x6 compatibility, so they match modern GPU needs. The Gigabyte P650B is ATX 12V v2.31, so it may lack the ATX 3.1 transient behaviour newer cards use. Also check modularity. Many budget picks here are non-modular, including the GIGABYTE P550SS, Gigabyte P650B, Ant Esports RX750 and RX550, so cables are fixed. Assume non-modular unless the spec says modular. Finally, active PFC (power factor correction) is listed on these models. Active PFC helps with unstable mains and is present on the Gigabyte P650B, GIGABYTE P550SS and Cooler Master MWE 550 V3. If a listing does not show active PFC, treat that as missing information.

• If you need cleaner cable routing, choose a modular PSU outside this ₹5,000 list or accept fixed cables.

which product suits which buyer

Small office or low-end gaming: Choose the Gigabyte P550SS or the Ant Esports RX550. The P550SS costs ₹3,746, is 550W, 80 Plus Silver and lists ATX 3.x / 12V-2x6 compatibility with active PFC. That makes it more efficient during long office use and handles some modern GPU current needs. The RX550 costs ₹3,200, is 550W, 80 Plus Bronze and is a white, non-modular option that fits tight budgets for basic gaming or office PCs.

Mid-range gaming and future upgrades: Pick the Gigabyte P650B or the Ant Esports RX750. The P650B is 650W, 80 Plus Bronze and costs ₹4,700, ₹4,944 with active PFC, giving extra continuous wattage for a heavier gaming build. The RX750 is 750W, 80 Plus Bronze and costs ₹4,190, offering clear headroom for more drives or stronger GPUs. For multi-screen trading rigs that run many monitors or many drives, prefer the RX750 or P650B for wattage headroom so the PSU does not run at high load. For buyers who specifically need ATX 3.1 support, pick the Cooler Master MWE 550 V3. It costs ₹4,389, is 550W, lists ATX 12V Ver. 3.1 and has active PFC, which matches modern GPU transient behaviour.

• Non-modular units are the norm here, so expect fixed cables and plan your case and cable routing accordingly.

what to do next: build or ask for a quote

Match the PSU wattage to the combined CPU and GPU peak draw plus peripherals. Peak draw means the highest power those parts use under load. If you plan a mid-range GPU with a 650W-class CPU and several drives or many monitors, pick a 650W or 750W unit for headroom so the PSU does not run near its limit. Use the Gigabyte P650B (650W, ₹4,700, ₹4,944) or Ant Esports RX750 (750W, ₹4,190) when you expect heavier gaming, editing, or multi-screen trading. For ATX 3.1 needs from modern GPUs, pick the Cooler Master MWE 550 V3 (550W, ₹4,389) or the GIGABYTE P550SS (550W, ₹3,746) which list ATX 3.x/3.1 compatibility.

If your planned parts fit a 550W system and you do not expect many drives or big future upgrades, continue building with a chosen PSU.
