220w PSU with an XFX 6600gt

post #1 of 12
Thread Starter 
So I know my PSU is underpowering my system, and I intend on upgrading once I make some money. However, when I run Aquamark3 with this card installed properly in my system, with my 2.8 OCed to 3.36, I get these crazy green triangles only in one scene. I also get this issue when I run Earth 2160. I know 2160 is extremely 3D intense, but is this normal on underpowered systems?

PS: my 12+ gets at max 12 amps

Uh....yeah......you REALLY need to stop using that PSU man. Your WAY past the red zone

I wouldn't use anything AT LEAST 350w, but 450 and up would be the best. Your also going to want to have a strong 12v rails to, anything 28amps and up.

I third. I had a crappy PS that came with my case - a 300W rated at 12A on the 12V rail. Voltages were always out of range. Upgraded to an Antec 480W and I've been rock solid ever since.

the problem is that it's a proprietary psu that's about 1/3 the size of a normal psu...any ideas on a replacement?

PS: what do you mean by the red zone?

if it is underpowering the system, how is that frying components???
post #9 of 12
Undervoltage is just as dangerous as overvoltage. With an undervoltage situation, the load causes a varying voltage signal that spikes to normal and then back again. It is this sort of spiking over time that damages components.
