HI guys, I am planning to add a Entry level graphic card to my HP pavilion a6340in PC. I have narrowed onto the ATI Raedon HD 5570 1GBDDR3 and the Nvidia GT 440 1GBDDR which comes under my budget.
My computer is 4 years old. here are its specifications:
Intel Core2DUo E4500 2.2Ghz
Windows Vista Starter 32 Bit
1GB DDR2 RAM, 160GB HDD. The problem is i cannot upgrade my 300W PSU and chose these cards as i heard they run in 300W PSU. However i just want to confirm with you guys .
Here are the PSU specifications:
These were the texts written on the PSU unit:
+5V= 25A, +12V= 19A,
+3.3V= 18A, -12V=0.8A, +5VSB= 2A.
+5V and +3.3V shall not exceed 175W.
+6V and +12V shall not exceed 268W.
in addition my Cabinet has one fan and a heat sink for the processor. Please let me know if both the GT440 and HD5570 are capable of running in my 300W PSU with the above specifications.
Yes, both the 5570 & the 440 can run from your power supply.
But performance wise, 5570 is faster than the 440 so go for the 5570 or even the 5670/6670.
Theoretically, your PSU can power 7750 800Mhz which is the most powerful graphics card that does not need 6PIN PCIe connector. But realizing that you got a 4 year old unbranded PSU, I would like to be a little more conservative in this recommendation so stick with 5570 or 5670/6670 at the most (if your budget allow).
