Is the Vento ATX-500H power supply suitable for the Gigabyte 770 2GD graphics card?

Question

Video cards

I have an old PC (but I have enough). And I wanted to upgrade my old video card, which is 11 years old (Radeon 3600) to a new one, but I wondered: Is my power supply suitable for the new video card now? I could not find an answer to this question on the Internet for a couple of days and found this site on which I am writing now. Thanks in advance
PS: (iron) i3-2100-perc. ASUS p8h61-m LX2 R2.0 motherboard. 8GB of memory (do not know which manufacturer) and the video card and power supply are written at the top

Answer 1

According to the first link on the manufacturer's website indicated

System power supply requirement: 600W

Your power supply is giving out

Power - 450 W

On the Yandex market in the characteristics:

Need additional power: yes, 8 pin + 6 pin

Your power supply does not have an "8-pin" connector:

Connectors
Motherboard connector type - 20+4 pin
Number of 4-pin CPU
connectors - 1 Number of 6-pin PCI-E
connectors - 1 Number of 15-pin SATA
connectors - 2 Number of 4-pin IDE connectors - 4
Number of 4-pin connectors Floppy-1

It is still possible to somehow dodge and connect via adapters (Molex-> 8pin), the system will start and show a picture. But stable operation is not guaranteed.

Answer 2

In addition to the old and insufficiently powerful PSU, your motherboard + processor: "when installing a Sandy Bridge processor, the slot will work as PCI-E 2.0"
That is, it makes no sense to install a video card with PCI-E 3.0, it will still slow down.
And, not, on the contrary: due to the "slowness" of the vidyuhi on the old motherboard and processor, your PSU will probably cope with everything. As 15432 recommends above , "you can still connect via adapters (Molex-> 8pin)," and then look after the fact.
