LukkiTheGamer · Oct 19, 2014

hey guys I just boight this new gpu and an new power supply 450 w. i had an gt 640 before and i never have had any problems with it. but when i isntalled all the drivers to the new one and the new one worked fine for like 5 mins and then suddenly the screen goes black and I only see the cursor when I move my mouse nothing else. Ive tried many different things but i cant make it work. I have no cd because my pc was built in the asus factory. so i cant repair or anything. everything powers upp correctly. my mouse and keyboard suddenly stops glowing and i get black screen.

for this set you wanna get at least 600 watt PSU.thats why you cant see anything cause there is not enough power to run your GPU r9 270x.

there are 450w units that can run such setup! however that really sounds like a power issue! which one do you have?

SFC 80+ 450 w

where are you buying from.? we maybe able to find a cheap but decent unit for your system!

LukkiTheGamer · Oct 19, 2014

Really ive found persons with much more power consuming products and still work with only 400 w

LukkiTheGamer · Oct 19, 2014

chris987 :

no matter where you find it just find an finnish store

then. good luck to fix you problem(you thing you know everything)

LukkiTheGamer :

Wattage is not everything. Some power supplies are advertised as 400W but can only deliver 200W continuously, while other 400W power supplies can deliver 500W continuously. Your power supply is of a cheap brand. Replace it as soon as possible. It can be as bad as the power supply letting higher voltage through than is allowed. This will damage your components permanently, and you'll have to change many other things than just your power supply.

Change that power supply as soon as possible. Give us your budget, and give us (one of the) store(s) you buy from. We'll assist you in choosing a power supply.

low quality psu units no matter what the labled power is, fail under most circumstances! a gaming pc equipted with a dedicated gpu with supplementary power need, demands at least a decent psu to operate seamlessly!

chris987 · Oct 19, 2014

LukkiTheGamer :

can you provide as some links of your preference?

kapitalistas :

The OP isn't necessarily wrong. I know my Antec HCG-400 would have no problems handling that configuration, but several cheap 450W PSU's wouldn't. OTH a 300W PSU would be enough to power up that system and load Windows, but it wouldn't be powerful enough to play GPU intensive games.

OP, have you tried using the old PSU (don't play games or run GPU stress tests)?

LukkiTheGamer · Oct 20, 2014

But guys I dont know if ive told you this but when it worked fine there for like 5 min I tried to put in my 2nd monitor and it was then it started to stay in blackscreen. I dont know what the problem is

LukkiTheGamer · Oct 20, 2014

And when I boot into safe mode and I use the gpu it works fine but with really bad resolution

NightAntilli · Oct 20, 2014

2 monitors = more pixels to draw = more power. Even when idle.

Having unstable power can cause a variety of problems. It's the primary thing that needs to be stable, and anything that can cause it needs to be eliminated. Not only for stability, but also for protection of your other components. Without stable power it's very hard to give any recommendation since it makes troubleshooting impossible.

Independent of whether it actually is the problem or not, our first recommendation is to change your power supply. If it doesn't solve the problem, we'll start looking further. Take it or leave it.
