Can we depend upon the PSU Calculator?

[Tian]

PSU Calculator je thik info daay, ta kotokhani sure. Er upor kotokhani depend kora jay?

[CvP]

most of the tech-savvy guys and sites (if not all) use PSU Calc.
questioning it is useless unless you have some solid proof.

I am agree with cvp, ta chara ei dhoroner calculations e 10% edik shedik hoitei pari which is negligible.

theres a catch

the PSU calculator will only calculate the maximum load of the GPU + CPU, along with the other components

however, keep in mind that you can never load the cpu + GPU a full 100%. i have asked many of the most knowledgeable programmers abroad to write a code for accomplishing this feat, but its simply not possible

that is because, when the cpu is fully loaded (the CPU itself can be loaded near 100%, if not fully) the GPU cannot be fully loaded since the CPU cannot feed enough data to the GPU

and the GPU has so many streaming processors that no application can load it 100% yet

so when calculating, combine the GPU + CPU and then subtract 10% from it

many people overlook this, hope this helps

edit: i realised some calculators do have the option of partially loading some components. good thing this calculator is, the ucc people shall not fool u again

Either i am entering wrong data, or the calculator is giving wrong result! It says that i need only 280w!!!

I use a normal motherboard[Intel], Normal PCI[8600gt] [passive cooling], 1 gb ram[DDR2], 2 normal cooler fans, 1 DVD rom, 1 HDD[sata]. No lan or soundcards. PLZ calculate this for me.

i think you are getting the correct answer.

EDIT: i tried it..with similar things: got 207W. it is correct.

[kabir_sharif2000]

Then why my PSI's recommended PSU capacity is 450w?[Its written on the packet]

Is it just for playing safe? Or for...?

[Thanks CVP]

[CvP]

Unless you are using highend GPU (like x8xx GTX/GX2) or multiGPU(e.g., SLi) or a lot of IDE/SATA drives, a true 450W PSU is more than enough.

[Tian]

Do you think Delux 450watt is enough to run 512MB 8800GT OC?

[Tian]

I use 2 SATA HDD, 2 DVD RW+-, a 280mm fan, a 140mm fan, two 80mm fan, and off course i'll overclock that 8800GT OC. Now tell me...

id say a good 450W power supply would do, from a reputable brand (i.e thermaltake, PC Power & Cooling, Antec etc)

and i assume you have a E8400 and 2GB RAM?

[Blue_fin]

my one shows 566 watt
so far the highest after bering overcloked

yes, for u i suggested getting a 600W, but honestly it will not ever reach 566W even when heavily loaded, and even a 520W PSU will be more than sufficient for ur PC
