If I get a higher wattage PSU, will it ruin my PC

vil_iam1 · Sep 15, 2014

High guys I'm going to upgrade my PC's GPU however I do not know what my PSU is (parents won't let me open it right now), and I was wondering if I were to upgrade my GPU and PSU, would it ruin my motherboard or burn out/melt the CPU?? All I want is to play Team Fortress 2 on medium or high settings. Would I need to upgrade to CPU as well?
My PC:
CPU: AMD FX(tm)-4100 Quad Core ~3.6 GHz
GPU (Integrated graphics): NVIDIA GeForce 7025 / NVIDIA nForce 630a
Mobo: ASRock N68-VS3 FX
PSU: ??
Thanks

No, it won't ruin your CPU/anything. But go for a good quality PSU. For your PC a 450W PSU is plenty enough with Graphics card. Seasonic makes one of the best PSUs out there.

Edit :- Be sure the Graphics card that you're getting, won't be bottlenecked by your CPU. Otherwise you'd just end up wasting money.

What you get for a PSU depends on what you get for a GPU. I'd suggest a GTX750Ti.

Get a good quality power supply from tiers 1, 2a or 2b of http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html

A 750Ti needs a 400W PSU per RealHardTech. I'd get a 500 - they are virtually the same price. eg Seasonic M12II 520 - $67 from Newegg.

Hey guys, turns out my pc already has a decent 550 w psu

and my PC doesn't have a graphics card (the gpu listed above is actually just integrated graphics) and I was thinking of getting either the NVIDIA Geforece GTX 750ti or the AMD Radeon R7 265. Which one of these do you think I'll get the most use of from gaming?? It seems the GTX is more power efficient but the R7 is better overall, correct me if I'm wrong...

What make and model psu?

vil_iam1 · Sep 18, 2014

Widetech 550W Power Supply Unit ATX PS-550TM

And does it get a mention in tier 1, 2a or 2b of http://www.tomshardware.com/answers/id-1804779/power-supply-unit-tier-list.html ?

Or has it got any good reviews? Is it a single 12V rail power supply? Is it bronze 80plus certified?

Or maybe after all its just a dud and you were using a bit of wishful thinking?

You just broke my brain... I'm still a computer noob and I have no idea what '12V rail power supply' or 'bronze 80plus certified' means... and no, it isn't even mentioned on the page, the psu came with the case (its a WideTech WT5285B with 550 psu) and I can't find anything about it online... my computer's been working for over 3 years now though so I assume it must be pretty good...

Power supplies that are bundled with cases are usually very very poor quality.

So in fact getting another PSU is a good thing. The one you have is poor quality.
